The Riverside Drive Bridge - Figueroa (1927/1939, 451’, aka. Dayton Avenue Bridge) The original 1927 structure was damaged in flooding in 1937-8 and was mostly replaced by the current bridge, reflecting the upper deck aesthetic of the original, but supported from below by a metal truss. This bridge is a favorite due to its contrasting elements or Beaux-Arts bridge design, Warren Truss construction and that ridiculous ninety degree turn in the middle of it. The Riverside Drive Bridge to Figueroa is slated for demolition and replacement in late 2010.
